cPanel is a powerful, yet user-friendly hosting/domain manager. cPanel has a simple-to-use interface that makes editing your hosting details extremely easy.
Through your cPanel (included with all HelioHost hosting accounts), you can
Create and manage e-mail addresses for your domain.
Check e-mail using either Horde, RoundCube, or SquirrelMail -or- alter MX records for use with another e-mail service (such as Google Apps - doing this will cause the cPanel built-in webmail clients to stop working)
Set-up e-mail clients for use with your e-mail addresses (through POP3/SMTP)
Update your HelioHost account information/password
Create and manage FTP accounts
Use the built-in cPanel file manager
